Circuit changes, additions, and regular replacements due to high-frequency switching are easy! This is a plug-in type multi-pole relay with long life and high reliability, medium capacity: RB□P-G□DC type!

The plug-in type multi-pole relay, medium capacity: RB□P-G□DC type, is equipped in auxiliary power devices and contributes to the accurate operation and safe driving of railway vehicles. Additionally, this relay adapts to the vehicle environment and helps improve system reliability while reducing maintenance frequency. The contact section of this product incorporates our original power lead switch "Bestact," which prevents oxidation and corrosion of the contacts, demonstrating high reliability under various usage environments compared to other products. Bestact achieves long-lasting products with excellent environmental resistance and vibration resistance due to our unique structure, which differs from conventional lead switches. Customers looking for relays or those dissatisfied with existing relays are welcome to consult us. For more details on the plug-in type multi-pole relay, medium capacity: RB□P-G□DC type, please download the "Relay/Proximity Switch/Limit Switch Specification Catalog" from our website and refer to the product page.

For over 40 years, our relays and sensors have been used in various markets where reliability and safety are required, such as in Shinkansen (bullet trains) and steel manufacturing. With advantages such as an electrical lifespan that is twice that of general relays and a failure rate that is 1/20 under minimal loads, our products contribute to improving equipment reliability while also reducing running costs by decreasing the frequency of replacements. Leveraging the excellent environmental resistance of our products, they perform well even in harsh environments, such as in vegetable factories where humidity is present.
